terribly disapointed

I can not begin to say how disapointed I am in samsung. My husband an I bought a new fridge. We entered the compition where you can win either a flight ticket or a stay at any protea hotel. I heard nothing for a week. Then a lady sent me an email asking for the serialnumber. I took a photo and sent it back. It as been a week an I have heard nothing. This is not a good experience with samsung. Dont make promises you cant keep. I truely hope this will get sorted out seeing that no one is replying to my emails.
